The iron phosphate NaZnFe2(PO4)3

Synopsis: NaZnFe2(PO4)3 features a new structural type built up from ZnO6 octahedra, FeO6 octahedra and FeO4 tetrahedra, linked together via the corners and edges of PO4 tetrahedra to form a three-dimensional framework, with tunnels running along [100]. Within these tunnels, Na+ cations occupy highly distorted cubic sites.

Nonasodium decatungstodysprosate pentatriacontahydrate

Synopsis: In the crystal structure of the title compound, the complex anion has approximate D4d symmetry, with Dy-O and W-O distances in the ranges 2.355 (6)-2.405 (6) and 1.715 (7)-2.369 (5) Å, respectively.

LiNa2AlF6: a powder structure solution

Synopsis: The crystal structure of lithium disodium aluminium hexafluoride, LiNa2AlF6, has been solved using X-ray powder diffraction. The monoclinically distorted structure is related to that of cubic elpasolite.

Neutron powder-profile study of chlorofluoromethane

Synopsis: Rietveld refinement of the neutron powder profiles of chlorofluoromethane, CH2ClF, shows that it crystallizes in the monoclinic system, with two formula units in the unit cell. The structure is close-packed and shows weakly hydrogen-bonded zigzag chains.
